<p>I can see valid uses of this but I also feel like a probabilistic calculator would be more useful.<p>e.g. the result for the 1 / [-1, 2] example doesn’t tell you how likely each value is and it clearly won’t be uniformly distributed (assuming the inputs are).</p>

<p>Here's my (hopefully) intuitive guide:<p>1. understand weighted least squares and how you can update an initial estimate (prior mean and variance) with a new measurement and its uncertainty (i.e. inverse variance weighted least squares)<p>2. this works because the true mean hasn't changed between measurements. What if it did?<p>3. KF uses a model of how the mean changes to predict what it should be <i>now</i> based on the past, including an inflation factor on the uncertainty since predictions aren't perfect<p>4. after the prediction, it becomes the same problem as (1) except you use the predicted values as the initial estimate<p>There are some details about the measurement matrix (when your measurement is a linear combination of the true value -- the state) and the Kalman gain, but these all come from the least squares formulation.<p>Least squares is the key and you can prove it's optimal under certain assumptions (e.g. Bayesian MMSE).</p>
